By selecting time and spatial scales suitable for regional characteristics and using accelerating moment release to predict the location of earthquakes, retrospective testing was conducted on 8 earthquakes with MS4.0 or higher in Heilongjiang province and adjacent areas since 2009. The results showed that 5 earthquakes observed accelerating moment release phenomenon before the earthquake, while in the other 3 were not observed. At the same time, before some earthquakes, it can be observed that there was a phenomenon of accelerated areas migrating towards the epicenter. This indicates that accelerating moment release has certain indicative significance for predicting the occurrence location of moderate earthquakes in Heilongjiang province and adjacent areas.
